Prussiano, Miami, Fla, assignor of fifty percent to Bernard Delia, Long Island, N.Y. Filed Italy 19, 1965, Ser. No. 473,031 4 Claims. (Cl. 77-62) This invention relates generally to a carpenters instrument and is more particularly directed to a door lock drilling and mortising device.
A principal object of the present invention is to provide a device for drilling the bores in the side and edge of a door for receiving a door lock wherein the bores are perfectly aligned with a minimum of effort and no opportunity for failure to bore aligned openings.
Another object of the present invention is to provide a device for drilling bores and mortising slots for a door lock, which device is simple in construction, inexpensive in cost and readily operated by non-skilled help to drill perfectly aligned bores with a saving in time as compared to the present conventional manner of marking aligned bores and then drilling them.
A further object of the present invention is to provide a device for drilling bores in a door for a door lock, which device will effect considerable savings in time, labor and degree of experience required of the user, yet the results attained by this device will be equal to, if not superior than that produced by highly experienced carpenters.
With these and other objects in view, the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawings but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.
In the drawings:
FIGURE 1 is a perspective view of a door lock drilling and mortising device embodying my invention shown mounted on a door with a drill motor and bit shown by dotted lines.
FIGURE 2 is a side elevational view shown with the drill removed from the device.
FIGURE 3 is a top plan view showing the drill supporting platform swung to a second position in dotted lines for drilling into the edge of the door.
FIGURE 4 is a front elevational view.
FIGURE 5 is a side elevational view similar to FIG- URE 2 with the platform swung to the second position for drilling into the edge of the door.
FIGURE 6 is a detailed cross sectional view taken along the line 66 of FIGURE 2.
FIGURE 7 is a cross sectional view taken along the line 7-7 of FIGURE 2.
Referring to the drawings wherein like numerals are used to designate similar parts throughout the several views, the numeral 10 refers to my door lock mortising device consisting generally of a mounting bracket A, adjustable clamps C for securing the device to a door 15, a drill support bracket B and a drill which is of conventional structure.
The mounting bracket A consists of a pair of U-shaped plate members 11 rounded at one end and having leg portions 12 whose ends are joined by a vertically disposed member 13 to maintain the plate members 11 in a horizontal, spaced and parallel relation. The leg portions 12 form slots 14 for receiving a door 15 that is to be mortised for a door lock. The U-shaped plate members 11 are of identical construction having a slot 16 extending medially along approximately their full length and are "ice each provided with a pillar 17 on which the adjustable clamp C is mounted.
Each of the pillars 17 consists of a rectangular support member secured at its base to the U-shaped plate member 11 at the end of the slot 14 along the exact centerline of the slot 14.
One each side of the support members of pillars 17 is a clamp member 18 and 28 having a smooth bore 19 and a threaded bore 20. A pin 27 is mounted on the pillar 17 and is received by the bores 19 to compel the clamp members 18 and 28 to remain in a parallel position with relation to the pillars 17 as the clamp members 18 and 28 are slid toward and away from the pillar 17 by a double screw locking member 21. The latter is provided with a knurled knob 20 for rotating the locking member 21. Since the adjacent clamp members 18 and 28 are provided with threads that are opposite, one being right handed and the other left handed and the locking member 21 having companion threads received by the bores 20 of the clamp members 18 and 28 are likewise opposite, upon turning the knurled knob 22, the clamp members 18 and 28 will slide toward or away an equal distance from the pillar 17 on the pin 27. To prevent sliding movement of the adjustment member 21, the bore 23 is slotted as at 24 at the center of the pillar 17 and the member 21 is provided with a peripheral slot 25 at its centre to form a key way for a key 26 which is inserted therein to permit rotation but not translatory movement of the adjustment member 21.
The slots 16 of the plate members 11 form a guide for a pair of posts 30 whose ends are received by the slots 16. Adjacent each end of each of the posts 30 there is a shoulder 31 against which a bar 32 rests. The bar 32 which extends between the posts 30 is provided with a bore 33 at each end for receiving the posts 30 in maintaining the posts 30 in fixed position with relation to each other. Washers 34 are positioned on the ends of the posts 30 on each side of the support plates 11. An adjustment bolt 35 being threadedly mounted on the ends of each of the posts 30 is received by a threaded bore 36 and is utilized to tighten or loosen the drill support bracket B on the support plates 11.
On the posts 30 there is slidably mounted for vertical movement a combined template and drill support B consisting of a template member 37 having flange portions 38 through which bores 39 extend. The posts 30 are slidably received by the bores 39. Locking bolts 40 secured to the template member 37 will fasten the drill support bracket B securely to the posts 30 when tightened and when loosened will permit sliding movement of the drill support bracket B on the posts 30 for adjustment thereof. At the lower portion of the template member 37, there is a drill support consisting of a pair of rods 41 extending horizontally at exactly right angle to the member 37 and having their ends fitted tightly into bores 42 in the member 37. A drill supporting platform 43 is slidably positioned on the rods 41. The platform 43 is provided with bores 44 which receive the rods 41 to permit the plat form 43 to slide therealong. On the platform 43 is a drill 45 fastened thereon with a drill bit 46 directed in the direction of a bore 47 in the template member 37.
In the normal operation of my door lock mortising device 10, the exact position at which the door lock is to be mounted is marked on the side wall of the door 15. My device 10* is then slipped over the edge of the door 15, the slot 14 receiving the edge of the door 15 with the door edge engaging the pillars 17 and the mark previously made on the side wall of the door 15 being positioned approximately midway between the support plates 11. The clamp members 18 are then tightened against the side walls of the door 15 by rotating the knurled knob 22 whereby the device 10 is fastened securely to the door 15.
Now, upon loosening the locking bolts 40 the template member 37 is slid vertically to the horizontal alignment with the aforesaid mark whereby the mark Will be found in the exact axial alignment with the template bore 47. The locking bolts 4d) are then tightened and the motor 45 is then energized. The drill bit 4-6 which extends into the template hole 47 will drill a hole at the exact position of the door lock.
When the hole has been drilled through the door, the adjustment bolts 35 are again loosened and the drill support bracket B is slid forwardly along the slots 16 until the template bore 47 is centered on the vertical centerline of front edge of the door 15. Since the horizontal position of the drill support bracket B has not been dis turbed on movement of the latter, the bore being drilled in the edge of the door will be in perfect axial alignment with the bore drilled in the side of the door. The adjusting bolts 35 are now tightened, the precise center of the template hole 47 marked on the door 15, the bit 46 removed and replaced by a smaller bit sized to receive the door lock bolt. The locking bolts 40 are loosened and the template member 37 is raised slightly to center the bit on the previously marked center line. The hole for the lock bolt is then drilled and a rectangular shaped slot is readily mortised about the bolt hole to receive the bolt plate by the appropriate adjusting of the vertical and horizontal position of the template member 37. The device is then removed from the door upon loosening the adjustable clamps C by unthreading the double screw locking member 21 and the door 15 has been properly drilled and mortised for receiving the door lock.
